Note: extremely rare and sought-after reverse type struck only at Siscia during the brief 2nd emmission (famous "Invictvs" series with INV[ictvs] in obverse legend).
The reverse legend underlines the close links of Siscia where this coin was struk with Probus, referring to the emperor as "noster" ("our").
